Top row: significance, S(τ), radial profiles of all (left panel) or only bright F > F_th (right) extended eROSITA sources, SW (blue diamonds, with solid lines to guide the eye) or CW (red circles, with dashed lines) stacked around massive clusters (bins 2–4). Also shown are the Poisson-statistics confidence levels (±{1σ, 2σ, 3σ, …}; dotted black curves), the control-sample median and the corresponding containment fractions (50%,16%,2.3%,… for SW; dot-dashed green lines), and the anticipated 2.2 < τ < 2.5 VS region (vertical yellow shading) based on previous stacked γ-ray (RK18) and radio (H23) continuum and discrete X-ray and radio source detections (I24). Bottom row: same as the top panels, but also including non-extended sources in the same F_min < F < F_max range.
